She has a devilish streak, playing pranks and teasing depending on the situation. When serious, she shows a very wise side, crafting strategies that overwhelm her opponents. In reality, she is Masachika's biological younger sister and one of the biggest otakus in the series. It's said that Masachika became an otaku primarily because of Yuki's aggressive proselytizing. Their parents are divorced; Masachika lives with their father and Yuki with their mother, which is why her surname changed to her mother's maiden name, "Suou." Believing there is no benefit to this fact being known, they pretend at school to be childhood friends who have known each other for a long time.
